Abstract: Provided are method and device for transmitting/receiving a downlink signal. A user equipment-specific reference signal (UE-RS) can be transmitted to a user equipment. A downlink control channel and a downlink data channel for the user equipment can share the UE-RS. Antenna port information about a transmission antenna port of the downlink control channel and/or a transmission antenna port of the downlink data channel is provided to the user equipment. The user equipment receives UE-RS(s) corresponding to the antenna port information and thus receives the downlink control channel and the downlink data channel.

Abstract: Provided are a method and a device for arranging a subframe structure of a short TTI according to the change in a control region in a wireless communication system. Specifically, a plurality of first downlink channels received during an sTTI and a second downlink channel received during a TTI are received. The number of symbols used for each of the plurality of first downlink channels is determined by a format indicator channel included in the first symbol of a subframe. Further, the plurality of first downlink channels are demodulated by using scheduling information included in each of the plurality of first downlink channels, and the second downlink channel is demodulated by using scheduling information included in a control region indicated by the format indicator channel.
